a guy from Benin(I can"t find this country through the Internet)sent me an e-mail last week.He said he want to do business with me , and I must accepted his payment terms,50%D/P and  balance of 50% D/A 30days .

      Do you think it would be a trap?

What i can do for you is to tell you that the country is exist.And you can find it in google.
